Long‐term trends in nitrate concentration in Iowa water supplies
Long‐term water quality studies of surface waters and groundwaters in Iowa have shown increases in nitrate concentrations in surface supplies and shallow wells. Nitrate concentrations in deeper wells have remained low and have exhibited no appreciable increases since 1950. The application of nitrogenous fertilizers to agricultural land appears to be the primary source of nitrates in water supplies.
